Temple Bar is the point in London where Fleet Street, City of London, becomes the Strand, Westminster, and where the City of London traditionally erected a barrier to regulate trade into the city. Today, the Royal Courts of Justice are located next to it. As the most important entrance to London from Westminster, it has long been the custom that the monarch stop at Temple Bar before entering the City of London, so that the Lord Mayor may offer him or her the City’s pearl-encrusted Sword of State as a token of loyalty. The term Temple Bar is also retained for the gateway designed by Christopher Wren which used to occupy the spot from the 17th to the late 19th century. Wren’s arch has been preserved and is now located in Paternoster Square next to St Paul’s Cathedral.
